Preheat oven to 300°F.
Line baking sheet with parchment paper.
Pour all 6 oz. of walnuts onto baking sheet.
Place baking sheet into oven and bake for 15 minutes. *Keep an eye on the walnuts starting around 10 minutes. You want them to be a bit shiny, slightly browned, and very fragrant.
Remove baking sheet from oven and allow to cool for 10 minutes.
Once walnuts have cooled, pour into a food processor or blender and blend or pulse for 30 seconds.
Continue to pulse in 30 second intervals while scraping down the sides of the food process or blender with a rubber spatula during breaks.
Blend to desired consistency, though I highly recommend blending until smooth and runny.
Store in airtight container in the fridge for up to 3 months.
